The wider storm

An upper level shortwave combined with a surface cold front and moderate instability produced multicellular thunderstorm clusters in eastern SC which led to damaging winds and large hail. An NWS survey team concluded that a macroburst occurred in central and eastern Orangeburg County which lead to widespread downed trees and powerlines and included significant damage to Lake Marion High School in Santee, SC.
